  • I've shot multiple Canon cameras side-by-side in an attempt to find color differences, with the oldest model dating back to 2003. (I never sold my first 10D.) When you control for all other ...
  • Imagine it's 2023, maybe 2024, and you work at NASA. You're the guy who gets an alert if InSight briefly wakes up and sends a signal. You get an alert on your computer and discover it not only woke...

  • At the right price, absolutely. Sharper out of camera and better high ISO, including better color response at high ISO (i.e not just noise improvements). It's going to be worse for reach limited ...
  • My 5Ds has reliable, fast AF on all of its points. I would expect nothing less given the AF and AE modules are 1DX derived. You can nitpick keeper rates on any DSLR and find the center is a little ...
  • That hasn't been my experience in large prints.
  • In practice DR on the 5Ds/5DsR is fine. It's actually a little better than Portra (>12ev range). You can push it further with some of the NR tools available today. Some scenes will still need a ...

    You have the same problem that you cannot compare them to the way they looked when developed, nor can you scientifically analyze the emulsion and base for signs of decay. Worse, your "perfectly ...

    The document describes how to achieve long term (i.e. potentially >100 years) storage by using B&W Panchromatic Separation film stored at the correct temperature, humidity, protection from ...
  • Replied in Nope
    Yes and no. I'd be willing to bet that one of unaccounted for variables is how well the film was developed and fixed. We treat commercial development as a fixed black box, but quality absolutely ...

    But can also be trivially verified as correct, down to the last bit. Every film dupe results in a loss of IQ. I would argue digital is better because of storage density and the ease with which ...
  • Replied in Nope
    "Best available practices" includes periodic inspection and duplication as needed. If best available practices are being employed then there's no question regarding data format because the files ...
  • Replied in Nope
    Because families are likely to pay to have their color negs separated into B&W films, then pay to store them in a climate controlled facility. This is getting ridiculous...
  • Replied in Nope
    To match with film you have to duplicate the film and inspect all copies periodically, replacing any copies which have degraded as you find them. This is a much more tedious and expensive task ...

    There's a reason I separated the post into two sections. "Let's assume a situation where caretakers actually care about long term storage and do everything right in both cases." And "Now let's ...
  • Replied in Nope
    Let's assume a situation where caretakers actually care about long term storage and do everything right in both cases. Film can be destroyed by fire, flood, and even fungus. And sometimes film ...
  • Go back and read the posts where that image came from. The left frame is Fuji Velvia 50 6x7 medium format scanned on a Howtek drum scanner . You can honestly say Velvia won this, but its opponent ...
  • T-stop transmissions would have impacted the meter, but these exposures are the same, they just trade shutter speed for aperture. (Unless you didn't use the meter at all and worked all camera/lens ...
  • Are you kidding? Most negative film shot in the history of film is not optimally exposed. It is corrected, as best as possible, by the lab. Even if we limit ourselves to "pros" this would be true, ...
  • It does when you have deep shadows and the meter is looking at a blue sky plus white/gray-ish buildings as "middle gray." On neg film if you want those shadows you've got to overexpose the ...
  • I'm pretty sure you did. From the point of view of a digital sensor. Most of digital's dynamic range is on the shadow side. Most of neg film's dynamic range is on the highlight side. You ...
